IMPORTANCE: Federal emergency authorities were invoked during the COVID-19 pandemic to expand clinical telehealth for opioid use disorder (OUD). OBJECTIVE: To examine the association of the receipt of telehealth services and medications for OUD (MOUD) with fatal drug overdoses before and during the pandemic. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used exploratory longitudinal data from 2 cohorts (prepandemic cohort: September 1, 2018, to February 29, 2020; pandemic cohort: September 1, 2019, to February 28, 2021) of Medicare Fee-for-Service beneficiaries aged 18 years or older initiating an episode of OUD-related care using Medicare Fee-for-Service data from the Centers for Medicare & Medicaid Services and National Death Index data from the Centers for Disease Control and Prevention. Data analysis was performed from September 19 to October 17, 2022. EXPOSURES: Prepandemic vs pandemic cohort demographic, medical, substance use, and psychiatric characteristics. MAIN OUTCOMES AND MEASURES: Receipt of OUD-related telehealth services, receipt of MOUD, and fatal drug overdose. RESULTS: The prepandemic cohort comprised 105 162 beneficiaries (58.1% female; 67.6% aged 45-74 years). The pandemic cohort comprised 70 479 beneficiaries (57.1% female; 66.3% aged 45-74 years). The rate of all-cause mortality was higher in the pandemic cohort (99.9 per 1000 beneficiaries; 7041 deaths) than in the prepandemic cohort (76.8 per 1000; 8076 deaths) (P < .001). The rate of fatal drug overdoses was higher in the pandemic cohort (5.1 per 1000 beneficiaries; n = 358) than in the prepandemic cohort (3.7 per 1000; n = 391) (P < .001). The percentage of deaths due to a fatal drug overdose was similar in the prepandemic (4.8%) and pandemic (5.1%) cohorts (P = .49). In multivariable analysis of the pandemic cohort, receipt of OUD-related telehealth was associated with a significantly lower adjusted odds ratio (aOR) for fatal drug overdose (aOR, 0.67; 95% CI, 0.48-0.92) as was receipt of MOUD from opioid treatment programs (aOR, 0.41; 95% CI, 0.25-0.68) and receipt of buprenorphine in office-based settings (aOR, 0.62; 95% CI, 0.43-0.91) compared with those not receiving MOUD; receipt of extended-release naltrexone in office-based settings was not associated with lower odds for fatal drug overdose (aOR, 1.16; 95% CI, 0.41-3.26). CONCLUSIONS AND RELEVANCE: This cohort study found that, among Medicare beneficiaries initiating OUD-related care during the COVID-19 pandemic, receipt of OUD-related telehealth services was associated with reduced risk for fatal drug overdose, as was receipt of MOUD from opioid treatment programs and receipt of buprenorphine in office-based settings. Strategies to expand provision of MOUD, increase retention in care, and address co-occurring physical and behavioral health conditions are needed.

IMPORTANCE: Women veterans increasingly seek care yet continue to face barriers in the Veterans Health Administration (VA), which predominantly cares for men. Evidence-based collaborative care models can improve patient access to treatment of depression, which is experienced at higher rates by women. While the VA has implemented these care models nationally, it is not known whether access improvements occur equitably across genders in primary care. OBJECTIVE: To examine whether the VA's national Primary Care-Mental Health Integration (PC-MHI) initiative (beginning 2007) expanded realized access to mental health care similarly for men and women. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included 5 377 093 million primary care patients assigned to 396 VA clinics that provided integrated mental health services nationally between October 2013 and September 2016. Data analysis occurred between May 2017 and July 2020. EXPOSURES: Clinic PC-MHI penetration, calculated as the proportion of clinic patients who saw an integrated specialist per fiscal year. MAIN OUTCOMES AND MEASURES: Estimates of mean VA health care utilization (mental health, primary care, other specialty care, telephone, hospitalizations) and median total costs for men and women. Multilevel models adjusted for year, clinic, patient characteristics, and interactions between patient-defined gender and clinic PC-MHI penetration. RESULTS: This study examined 5 377 093 veterans (448 455 [8.3%] women; 3 744 140 [69.6%] White) with a mean (SD) baseline age 62.0 (16.6) years. Each percentage-point increase in the proportion of clinic patients who saw an integrated specialist was associated with 38% fewer mental health visits per year for women (incidence rate ratio [IRR], 0.62; 95% CI, 0.60-0.65), but 39% more visits for men (IRR, 1.39; 95% CI, 1.34-1.44; P < .001). Both men and women had more primary care visits (men: IRR, 1.40; 95% CI, 1.36-1.45; women: IRR, 1.22; 95% CI, 1.17-1.28; P < .001) and total costs (men: β [SE], 2.23 [0.10]; women: β [SE], 1.24 [0.15]; P = .06), but women had 74% fewer hospitalizations than men related to clinics with mental health integration (IRR, 0.26; 95% CI, 0.19-0.36 vs IRR, 1.02; 95% CI, 0.83-1.24; P < .001). CONCLUSIONS AND RELEVANCE: While greater outpatient service use for men was observed in this study, PC-MHI was associated with a decrease in mental health specialty visits (and hospitalizations) for women veterans, potentially signifying a shift of services to primary care. With increasing patient choice for where veterans receive care, the VA must tailor medical care to the needs of rising numbers of women patients. Differences in health care utilization by gender highlight the importance of anticipating policy impacts on and tailoring services for patients in the numerical minority in the VA and other health systems.

OBJECTIVE: To investigate associations between the percentage and severity of mental disorders (MD) and three different primary health care (PHC) strategies in Brazil: traditional care (TC), the Family Health Strategy (FHS), and FHS with shared mental health care (FHS+SC). METHODS: Random samples were selected from three different areas of a Brazilian city. Each area was served by a different PHC strategy (TC, FHS, or FHS+SC). Five mental health professionals, blinded to the type of PHC strategy delivered in each area, conducted interviews using the Mini International Neuropsychiatric Interview (MINI) and other specific instruments to assess the prevalence and severity of MD. RESULTS: 530 subjects were interviewed. The TC strategy was significantly associated with a higher percentage of MD when compared to FHS and FHS+SC. These results were not affected by adjustment for sociodemographic variables. The difference in prevalence of MD between the two FHS areas (with and without SC) was not statistically significant. No significant differences in MD severity were observed across the three PHC strategies. CONCLUSION: Areas covered by FHS showed a lower percentage of MD than those covered by TC. Presence of SC did not influence the prevalence of MD, suggesting that mental-health training of FHS teams may have minimized the influence of SC.

Background: Men who have sex with men (MSM) have elevated rates of substance use disorders (SUDs) and differences across sociodemographic sub-groups of MSM are associated with a greater risk of deleterious outcomes. Although studies have shown that MSM report greater rates of polysubstance use relative to other adult populations, the associations between sociodemographic characteristics and both acute substance use and substance use severity among methamphetamine-using MSM are unknown. Objectives: The present study examines associations between sociodemographic characteristics and (a) recent substance use and (b) SUD severity. Method: From March 2014 to January 2016, 286 methamphetamine-using MSM were recruited to complete a baseline Audio Computer-Assisted Self-Interview (ACASI) assessment and the SCID MINI. Multivariable analyses employed generalized structural equation modeling given the non-continuous nature of the endogenous variables. Results: All measured sociodemographic characteristics except gay self-identification were significantly associated with recent substance use (all ps ≤ .05), and all characteristics except current homelessness were significantly associated with diagnostic SUD severity (all ps ≤ .05). However, nuanced risks were observed in participants' use of specific substances regarding recent substance use and substance use severity. Conclusion: These results suggest that multiple factors contribute to the risks of SUD severity among methamphetamine-using MSM. As such, these results are useful in the tailoring of clinical and psychosocial intervention strategies that serve this and other high-risk populations.
